88% | With sodium carbonate In 1,4-dioxane; water at 80 - 100℃; | To a stirred solution of 2-trifluromethyl-bromobenzene (0.7 g, 2.75 mmol) and 4-carbaldehyde boronic acid (0.5 g, 3.3 mmol) in dioxane (20 ml_) under nitrogen at 80 5C was added Pd(PPh3)4 (0.05 g) followed by the addition of a solution of Na2CO3 (0.7 g) in H2O (5 m). The mixture was stirred at 100 5C for 6 h. The solvent was evaporated and the residue was diluted to 50 ml with EtOAc and washed with H2O. The solvent was devaporated to dryness and the residue was purified by FCC (SiO2) to give the title compound (0.61 g; 88percent), as creamy solid. 1H-NMR (CDCI3) 7.49 (d, 1 H, J = 7.41 Hz); 7.48 (d, 2H, J = 8.13 Hz); 7.61 - 7.53 (m, 2H); 7.76 (d, 1 H, J = 7.8 Hz); 7.91 (d, 2H, J = 8.34 Hz); 10.07 (s, 1 H). |
